LOCK-HINGE.

SPECIFICATION forming part of Letters Patent No. 457,556, dated August11, 1891.

Application filed February 14, 1891. Serial No. 381,518. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT G. PIKE, J r., a citizen of the UnitedStates, residing at the city of Brooklyn, in the county of Kings andState of New York, have invented a new and useful Improvement in MetalHinges for Blinds, Shutters, Doors, and the Like, of which the followingis a true description, reference being had to the accompanying drawings,which make a part of this my specification.

This invention relates to hinges, and is especially adapted forconnecting shutters to window-frames; and the objects in view are toprovide a hinge of extremely cheap and simple construction and whichwill be selflocking, and adapted for retaining the shutter at anydesired anglethat is, either opened or closed or at any intermediatepoint.

Other objects and advantages of the invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the claims.

Referring to the drawings, Figure l is a perspective of a portion of ashutter and window-frame, the former being shown closed and connected tothe latter bya hinge constructed in accordance with my invention. Fig. 2is a horizontal section through the hinge. Fig. 3 is a verticallongitudinal section through the pintle of the hinge, the shutter beingshown half open.

Like numerals of reference indicate like parts in all the figures of thedrawings.

1 designates the shutter, and 2 the windowcasing. From the casing, nearthe upper end thereof, extends a Vertical pintle 3, which engages and isreceived by a conical eye 4., formed upon the outer end of a hingesection or leaf 5, the latter being secured, as shown, to the face ofthe shutter. Near the lower end of the shutter there is secured to theface a leaf or hinge-section 6, which latter is reduced at its outerend, forming a shoulder 7, and above the same terminates in an elongatedeye 8, longitudinally disposed with relation to the leaf 6. Asecuring-plate 9, secured to the window frame or casing, is providedwith an oppositely-disposed horizontal semicircular bracket 10, fromwhich rises a concentrically-located vertical pintle or stud 11. The

periphery of the bracket is provided with a series of radial notches orrecesses 12.

In practice the elongated eye 8 receives the I pintle 11. The partsbeing in the position shown in Fig. 1, it will be observed that theshutter is closed and that the shoulder 7 rests within and is engaged byone of the notches 12 of the bracket, whereby it is prevented fromswinging upon its pintles. In order to open the shutter, the same isdrawn laterally, so that the shoulder 7 is disengaged from itsengaging-notch, such lateral movement upon the part of the shutter beingpermissible by means of the conoid form given the upper hinge-eye. Afterthe shoulder has been thus disengaged it will be obvious that theshutter may be swung open, and if freed will drop into the firstsucceeding notch. However, by retaining the shutter in the positionindicated the shoulder will swing past the numerous notches until theshutter is freed or swung back against the wall of the building, when itwill take into an adjacent notch. It will be observed that the shuttermay be locked in any of its open or closed positions and held at anyangle desired against accidental slamming by the wind. YVhen open, itmay be readily closed by pressing against the rear or hinge edgethereof, thus forcing the lock ing-shoulder 7 out of engagement with itsengaging-notch, after which the shutter may be simply swung to.

It will of course be understood that the number of notches may beincreased or diminished over those herein shown.

Having described my invention, what I claim is 1. The herein-describedhinge, consisting of a securing-plate, a bracket having a circular edgeextending therefrom and provided with a vertical stud, and a hinge-leafreduced at its rear end to form a shoulder for engaging notches formedin the bracket and terminat ing above the same in an elongated eye forloosely receiving the pintle, substantially as specified.

2. The combination, with a shutter and a window-frame, of a pintlelocated upon the window-frame near the upper end of the shutter, ahinge-leaf secured to the shutter and terminating in a conoid-shaped eyefor engagduced to form the shoulder 7 and above the ing the pintle, asecuring-plate connected to same terminating in the elongated eye 8,sub- IO the window-frame near the lower end of the stantially asspecified.

shutter and provided with a semicircular 5' bracket having a notchedperiphery and a ROBERT G. PIKE, JR.
